    100kg person is 80kg water -> 20kg not water

    For them to be 90% water -> 20kg not water of a total of 200kg -> 180kg water

    180kg water after drinking - 80kg water before drinking = 100kg water must be consumed

      Yup, that was my exact thought process. You even chose the same numbers my brain did.
